2 Claims.

5 products have been delivered from it or giving a signal. The principal object of the invention is to provide for closing the signal or stopping circuit pneumatically or mechanically when the desired number of products have been delivered. The invention involves several ways of accomplishing these results all designed to provide for carrying them out efficiently and with very little addition to the mechanism.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing in which Fig. 1 shows diagrammatically the connections for controlling a circuit in accordance with this invention by pneumatic means, and

Fig. 2 is a similar view showing mechanical control.

The invention involves the use of a counter having several dials adapted to be set and connected so as to close a circuit when a predetermined number of products have been delivered. In some forms shown this is accomplished automatically, although some features of this invention are of importance in those cases where the press-man stops the press when the count registers the proper number of papers and a signal is given thereby.

In the form of the invention shown in Fig. l the cutting cylinder of the folding couple of a printing press is provided withan eccentric -11 which raises a rod 12 once during each revolution of the cutting cylinder. This is connected up with the counter so as to cause the counter lever 13 to be operated and count one paper for each revolution. At the beginning of the run, the several dials of the counter 14 are moved by hand to a position which will indicate the number of papers required for this particular run.

In this case each counter disc 50 is provided with a projection 51 and they are set as previously indicated. As these discs rotate, each one finally lifts a plunger 52. These plungers are provided with valves on their ends controlling outlets 53 for air in a compressed air pipe 54. As long as any of these valves are open, air will escape. As long as the air escapes, the pressure in a cylinder 55 will not be enough to lift thepiston 56 therein against its spring 57and move the contact 21 against the contacts 20 in the circuit 22. When the proper number 01' papers has been delivered, all the plungers are raised and the various valves closed. There will be an increase of pressure in the air cylinder 55 and the circuit 22 will be closed so as to bring the press to a stop or give an audible or visible signal.

In the form shown in Fig. 2, the arrangement is mechanical but the results are substantially the same. The cutting cylinder is provided with a crank 41 which by a link 42 operates the counter arm 13 as before. A plunger 43 is provided with a base having several projections 44, each adapted to rest on one of the counter discs 45. Each counter disc has a recess or notch 46. These are set exactly the same as in Fig. 1 and when the notches are all brought into vertical position, the several lugs 44 will register in them and the plunger can descend. As long as any one of them is held up by the circular part of its counter disc, the plunger is held up and the contacts 20 of the circuit 22 are kept open.

It will be seen that in both these forms the counter is itself provided with means by which the circuit can be connected up by the counter, when the desired number of products have been delivered, and the press stopped.

Although I have illustrated and described only two forms of the invention, I am aware of the fact that other modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but what I do claim 1. The combination with a counter having dials adapted to be set to show a predetermined number, of pneumatic means comprising a source of compressed fluid, a pressure chamber, means in the pressure chamber responsive to the pressure therein and a fluid line provided with leak ports connecting said source and said chamber, and valves for said leak ports movable into port closing position when the dials have turned to show that the predetermined number has been reached, thereby causing the pressure in saidchamber to increase and the means therein to operate.

2. The combination with a counter having dials adapted to be set to show a predetermined number, said dials having projections thereon. of pneumatic means comprising a compressed fluid line having leak ports'therein, valves for said ports, a pressure chamber connected to said line, a shiftable means controlled by the pressure chamber, the projections on said dials being so located that when the dials have turned to show that the predetermined number has been reached, they will actuate the valves to close the ports whereby the pressure to said chamber will build up and actuate said shiftable means.
